> 
> Network Associates has discovered an e-mail virus similar to the
> Melissa virus that company officials said they believe is even more
> dangerous than its predecessor.
> 
> Dubbed Papa, the new virus is an Excel virus that sends itself in
> the same manner as Melissa, but sends itself to the first 60 people
> in a user's address book compared to 50 with Melissa. In addition,
> Papa sends an e-mail out every time the virus is activated. Melissa
> only sends the message the first time it is opened.
> 
> This time the subject line claims the message is from "all.net and
> Fred Cohen." The body of the e-mail, which contains an attached
> document titled "path.xls," then instructs the user not to disable
> the macros, which is how the virus is activated.
> 
> According to Sal Viveros, group marketing manager for total virus
> defense at Network Associates, the most disruptive aspect of Papa is
> the fact that it "pings" an as-yet-undetermined external site to
> make sure there is an available Internet connection. The practice of
> pinging is not unusual, but Papa pings so many times that it brings
> the network down.
> 
> The biggest concern from a corporate security standpoint is that any
> document infected with the virus and then e-mailed to another party
> is distributed in the same way the Melissa virus is, leaving
> companies vulnerable to having confidential documents distributed
> unknowingly.
> 
> Viveros believes Papa was written by a different person than the
> author of Melissa, but that it uses the original virus as a road
> map. This practice of using similar mechanisms to deliver more
> destructive payloads is not unusual, noted Viveros, which could mean
> a string of such similar viruses could be on the way. Variants,
> however, should be less disruptive because virus-detection vendors
> know what they are looking for. Network Associates expects to post
> software for detection and cleaning of the Papa virus by Monday afternoon.
> 
> The Melissa virus first sprang up in countless e-mail inboxes around
> the world on Friday, replicating itself to end-user address books
> and sending an exhaustive list of pornographic Web sites to everyone
> therein.
> 
> According to Viveros, Melissa is the widest spreading virus he has
> ever seen, hitting approximately 80 percent of Network Associates'
> major customers, which amounts to almost 100 companies. A significant
> number of those were forced to take their e-mail systems down.
> 
> The Melissa virus hampered -- and in some cases entirely shut down
> -- e-mail systems for companies the world over. Microsoft, for
> example, put a halt to all outgoing e-mails throughout the company on
> Friday to guard against spreading the virus.
> 
> "Viruses are a serious issue. We and our partners had to respond
> pretty quickly last week and now have clear guidelines on how to use
> the [Exchange and Outlook] software to block the message and stop it
> from getting around. That message [of a fix] is getting out, and the
> virus has been addressed," said Bill Gates, CEO of Microsoft, in
> Redmond, Wash., on Monday.
> 
> "These things are very rare. The incidence is going down, but
> there's work for us," Gates said.
> 
> At risk are Microsoft Exchange Servers running Microsoft Outlook.
> With an ever-changing subject heading of "Important Message From
> [end-user name]," the attachment to the e-mail is a document entitled
> "list.doc" with a body of text stating, "Here is that document you
> asked for ... don't show anyone else ;-)."
> 
> Upon opening the attachment, Microsoft Word 97 will ask if you want
> to disable the macros, to which you should reply yes, or the e-mail
> will automatically be sent to the first fifty names on each company
> mailing list.
> 
> "If you don't disable the macros, the virus resends itself to
> everyone in [your] address list," said John Berard, a spokesman for
> Fleishman Hillard, which was infected by the virus and inadvertently
> spread it around.
> 
> In addition, the virus automatically changes the security settings
> of an infected system to the lowest possible setting, a slick move
> that has IT managers wondering if they will have to manually reset
> every infected PC in their enterprise.
> 
> Dan Schrader, director of product marketing at anti-virus software
> maker Trend Micro, said the virus is easy to detect and not
> destructive in nature. But it can cause serious bandwidth
> constraints and contains several quirky characteristics.
> 
> One of those is a hidden message from the popular TV series "The
> Simpsons" that is inserted into any open documents whenever the date
> and the time - 2:29 on the 29th for instance - match.
> 
> A fix for the Melissa virus is now available from most major
> anti-virus software vendors.
